Tried booking Tatkal today for MAS-HWH.
In the first 1 min I was at the payment page. When I pressed 'Buy' which would have redirected me to the secure seal password page (I was purchasing through Visa Debit), it went to error.
There was quite some available then.
The above repeated when status was WL 4/4.
Ultimately...
more... secured to get myself a WL'ed ticket at status WL 9!! :(
